WATEBEROOF GLUE OR CEMENT AND METHOD OF MAKING THE SAME.

Patented J an. 12, 19159 No Drawing. Application filed March 24, 1911,Serial No. 616,576. Renewed'ltiay 22, 1914. 8eria1 No.

To all whom it mayconcem:

\ a'strong and thoroughly reliable and pracits moisture, can be ticalglue or cement suitable for gluing paper, wood, leather and variousother substances, which is impervious to water and quickly and easilyprepared, for use, and 1s inexpensive to manufacture. l

The glue or cement is composed of the following ingredients inapproximately the,

proportions stated, to-wit: Animal glue, 90 ounces; zinc oxid, 8 ounces;chromic oxid, 8 ounces; lead carbonate, 16 ounces; and sufficient water,to make gallons of the solution, to which is added about 60 to 90 poundsof animal glue.

The product is made in the following manner: The first named amount (90ounces) of; glue is dissolved in 15 gallons (more or less) of water,after which the zinc oxidis added and the solution heated, preferably ina Water bath, for about ten minutes. -The chromic oxid and 5 gallons.(more or less) of water are then added and the mixture is boiled forabout 5 minutes.

Then the lead carbonate and 10 gallons "(more or less) of water areadded and the mixture stirred thoroughly whereupon lead oxid isprecipitated. After the precipitate has settled, the clear solution ispreferably,

though not necessarily, drawn ofi'. Sixty to ninety pounds of glue isthen added to the solutio J The above namedproportions of theingredients and the described method of makng theglue can be variedsomewhat and still produce a glue which is satisfactory for somepurposes, but the described formula and method produce the inostsatisfactory glue or cement for general use.

described is of a'jelly-like consistency and of whitish color. Beforeusing the glue it is heated until it is thin enough to be readily spreadin a thin even coat on the surfaces to be glued together. When the gluesets it forms a very strong adhesive, which is practically unaffected byWater or moisture."

I claim as my invention:

1. A waterproof glue or cement comprising the following ingredients inapproximately the proportions stated, to-wit:- glue, 90 ounces; chromicoxid, 8 ounces; lead carbonate, 16 ounces; sufficient water to make asolution of 30 gallons, and additional glue, to 90 pounds, substantiallyas set forth.
